The Winston family soldiers tried to stop Diana from walking towards the Dragon yet their efforts were in vain. Ethan didn't stop her but followed her behind. Although the Dragon's physique and innate ability would give the dragon an edge if they battled, he was confident enough in his strength to defeat the dragon if it tried to harm them.
"Relax everyone, I know him" Diana waved off at the guards to lower their weapons. Taking a few more steps, she came closer to the point where Ethan could sense the heat radiating from the dragon's body. They both looked up, in Ethan's eyes, there was a mix of amazement and caution while in Diana's eyes, there was nothing but kindness and warmth.
She reached out as Nightmare gawked reluctantly for a moment before slowly lowering his head to graze her hand with his face. The soldiered were stunned to see Diana tame such a majestic terrifying creature.
